Limited or No Connectivity Creteria
What checks does Windows XP/7 do to determine if a computer has limited or not connectivity? I realize Windows XP and Windows 7 perform different checks. I believe they ping a certain address and probably use DNS to some extent. But I was looking for the exact things they check to test connectivity.

McKnife,
Have you checked to see if NCSI is configured correctly on your machines? I personally have not had any obvious problems with the feature.

It is. But maybe I am wrong about what DNS request can be succesfully answered through our proxy. Will check tomorrow.
Ok, I was unaware that the DNS request (nslookup dns.msftncsi.com) will be served without internet access so that alone lets Windows Vista decide it has internet access.

Let me tell you what about these superduper checks: On many (not all) of my networked computers, the nw-connectivity icons tell me "local network and internet access" - while these workstations are not connected to the internet. I don't know what this crappy check does, but it cannot reach files like http://www.msftncsi.com/ncsi.txt for sure. These computers are definitely offline (= not able to go online). So don't count on it.
